The Duke of Cambridge proudly held his baby son in his arms as the new family arrived at St James's Palace while mother Kate, 31, greeted the Archbishop of Canterbury wearing an ivory, crepe full skirt and a matching peplum jacket by Alexander McQueen.

Alexander McQueen, the London-based label helmed by Manchester-born Sarah Burton, has become one of the Duchess's most trusted fashion brands. Her wedding gown was created by Burton, and she has worn pieces by the label to the Queen's Silver Jubilee as well as on numerous public engagements.
